Dear Attorney General Holder:
I am writing to express my serious concern about the continued operations of the sex tour industry in the United States and the need for prosecutions of sex tour operators by its Department of Justice.
Sex tourism is a criminal act and a serious worldwide problem, one that disproportionately exploits and harms women—and very often children—while it supports a multi-billion dollar industry in human trafficking. While five U.S. states currently have laws that make operating sex tours a form of pimping, most other states’ promoting prostitution statutes, which do not explicitly address sex tourism, resemble the previous New York law under which Big Apple Oriental Tours owners Norman Barabash and Douglas Allen were acquitted in January 2009. This makes it all the more urgent that the US Department of Justice prosecute sex tour operators under the Mann Act and Travel Act. One such person is Gunter Frentz, the owner/operator of G.F. Tours (formerly known as G&F Tours). G.F. Tours organizes sex tours emanating from within the U.S. and openly advertises its sex tours online.
I would therefore respectfully urge you in your capacity as Attorney General to clarify to all federal prosecutors that the Department of Justice policy is to prosecute U.S. based sex tour operators, and to begin an immediate federal investigation into the activities of Gunter Frentz, the owner/operator of G.F. Tours, and other sex tour operators for knowingly and openly transporting individuals to other countries with the intent of engaging in prostitution in violation of the Mann Act and Travel Act.
Thank you for your attention.
